nope, that's a misconception ,
OP only grants OP permission assigned to be granted to OP,
if you set default to false, that meant no one will have it unless you explicitly granted it said node
via plugins like pureperms or using your own plugins

then you could create a plugin help, wording it differently like
"i have a plugin which have permission "default:" to false which i need that to prevent anyone other then me to use it, but how can i allow console to use it" or something like so
but i doubt there will be any useful advices, they would mostly go by:
editing it so default is true and use a perm manager to remove it
editing it so it allows console to run the command
ask the plugin developer to allow console

if you can code, which i assume you can because this is in development section, try editing it so it allows console to run the command is my best idea
